POR is % of reading.

2

Nonlinearity is defined as the maximum deviation (in percent error) from a straight line connecting the readings at 0 V and at 200 mV rms.

3

After fourth-order error correction using the equation

where y is the corrected result and x is the device output between 0.01 V and 0.3 V.

4

Crest factor error is specified as the additional error resulting from the specific crest factor, using a 200 mV rms signal as a reference. The crest factor is defined as

5

DC offset does not limit ac resolution.

6

Value is measured

with respect to COM.
